How can I programatically use Google Voice's "Direct Access Numbers" feature?
Google Voice apps on Android and iPhone have can directly dial out a number that connects to the target number.
This is different than the two ways that I know of connecting a call:
1) use the (undocumented) API to call you first, then GV connects the target party. 2) call the voicemail#, pause, , pause, <2> ,
Both of those methods provide a less than ideal experience.
